Abstract

"TRANSDUTOR DE POSIçãO SEM FIO COM SINALIZAçãO DIGITAL". A presente invenção refere-se a um aparelho para rastrear um objeto que inclui um transdutor de posição, o qual está adaptado para ser fixo no objeto. O transdutor de posição inclui um microcontrolador digital, o qual inclui uma pluralidade de pinos de saída, e o qual é operável para gerar uma saída digital alternada em uma freqüência selecionada em pelo menos um dos pinos de saída. Pelo menos uma antena de transmissão está acoplada diretamente no pelo menos um dos pinos de saída, de modo que a pelo menos uma antena transmita um campo magnético na freqüência selecionada em resposta à saída digital alternada. Um sensor de campo detecta o campo magnético e gera um sinal em resposta a este. Um processador recebe e processa o sinal de modo a determinar as coordenadas do transdutor de posição.
